hey guys, i wanted to know if there are any good performance upgrade shops like renntech in the nyc area?
and has anyone upgraded their sl500 to about 400 hp?

also what is the least expensive and most effective way to increase the sl500's hp to about 400?

results and experiences are welcome

 

RENNtech ECU upgrade for the SL500 yields just 10 additional horsepower, from 302 to 312. For the princely sum of $15,900, you can add a supercharger to boost performance to 443 hp.

There is also this place in Brooklyn:

Sovereign Motorcars
1810 Shore Pkwy
Brooklyn, NY 11214

thanks Jackstraw, I'll look into it, but 16k is a bit much

 

Talk to Jay at Auto Addiction. He's a bit outeast in Lindenhurst but a really nice guy. Sells and installs RENNtech and other parts. See what he can do for you. 631-592-4333.

 

We have done two KLEEMAN s/c in SL500 with great results. Call me if you got questions, 201-988-2309 - Anthony

 

We may have met at the meet in LI I had my black SL55 with me. If you want I help you out with performance. My SL 55 has a full kleemann setup on it. Car is a missile.

We will get you about 35 hp from an ECU tune and K&N filter. Its's not 400, but it's a nice set up and its a hell of allot cheaper than 15K!
